On-Demand Localization in Microservice Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microservice application environments face challenges in efficiently providing localized user interface labels across multiple services, leading to increased network calls and bandwidth consumption.
Innovation Solution
An on-demand localization system that uses a centralized REST API to retrieve localized user interface labels for each module in a single call, reducing unnecessary network traffic and improving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If locale-specific bundles are hosted at one microservice to reduce network calls, then the number of network calls is reduced, but the bundle size grows exponentially making it unwieldy and difficult to maintain
Solution Approach 1:
The patent segments the monolithic application into multiple microservices, each responsible for specific functionality and its own locale-specific bundles. This allows localization data to be distributed across services rather than consolidated into one large bundle, reducing both network call overhead and bundle complexity.
Solution Approach 2:
The patent extracts locale-specific information from the main application flow and handles it separately through an on-demand localization service. This extraction allows the system to retrieve only the specific localization data needed for each user interface element, rather than transmitting entire locale bundles.
2Adaptability or versatility
If large locale bundles are loaded onto the client browser, then all localization needs are met, but bandwidth and browser memory are consumed excessively
Solution Approach 1:
The patent implements local quality by having each microservice maintain its own locale-specific bundles locally. This allows the client to retrieve small, targeted portions of localization data from specific services rather than loading complete locale bundles, reducing bandwidth and memory consumption while maintaining full localization adaptability.
Solution Approach 2:
The system performs preliminary action by pre-configuring each microservice with its own locale bundles, so that when a user requests localization, the data is already prepared and available at the service level. This eliminates the need to transfer large bundles to the client, as only small, specific localization strings are retrieved on-demand.
3Reliability
If each page retrieves locale-specific information from all comprising services, then complete localization is achieved, but multiple network calls are required
Solution Approach 1:
The patent introduces an intermediary localization service that coordinates between the client and multiple microservices. This intermediary receives localization requests, determines which specific services have the required locale data, and orchestrates the retrieval process efficiently. This ensures complete localization while minimizing network calls by avoiding redundant requests to all services.

AI summary
In accordance with an embodiment, described herein is a system and method for providing on-demand localization in a microservice application environment. Generally described, an on-demand localization environment enables the system to serve localized user interface labels for an existing, e.g., monolith application, on-demand-without impacting the existing setup of the application or its present means of handling localizations. The described approach can ensure that only the localization which is needed for a particular user interface or visited page is served, without incurring additional round-trips back to the server for user interface messages that could have been served from the client. For applications and user interfaces comprising more than one module, the system can retrieve the localization for each of the modules in a single call.
